Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Four bits of data from two sources can be selected using the common Select and Enable inputs. The four outputs present the selected data in the true (noninverted) form. The LVX157 can also be used as a function generator. ■ Input voltage level translation from 5V to 3V ■ Ideal for low power/low noise 3.3V applications ■ Guaranteed simultaneous switching noise level and dynamic threshold performance Ordering Code: Order Number 74LVX157M 74LVX157SJ 74LVX157MTC Package Number Package Description M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices are also available in Tape and Reel.

The particular register from which the data comes is determined by the state of the Select input. A less obvious use is as a function generator. The LVX157 can generate any four of the sixteen different functions of two variables with one variable common. This is useful for implementing gating functions. The LVX157 is a quad 2-input multiplexer. It selects four bits of data from two sources under the control of a common Select input (S). The Enable input (E) is active-LOW. When E is HIGH, all of the outputs (Z) are forced LOW regardless of all other inputs. The LVX157 is the logic implementation of a 4-pole, 2-position switch where the position of the switch is determined by the logic levels supplied to the Select input. The logic equations for the outputs are shown below: Za = E • (I1a • S + I0a • S) Zb = E • (I1b • S + I0b • S) Zc = E • (I1c • S + I0c • S) Zd = E • (I1d • S + I0d • S) Logic Diagram www.fairchildsemi.com 2 Recommended Operating Conditions (Note 2) −0.5V to +7.0V Supply Voltage (VCC) DC Input Diode Current (IIK) Supply Voltage (VCC) VI = −0.5V −20 mA −0.5V to 7V DC Input Voltage (VI) 2.0V to 3.6V Input Voltage (VI) 0V to 5.5V Output Voltage (VO) DC Output Diode Current (IOK) 0V to VCC −40°C to +85°C Operating Temperature (TA) VO = −0.5V −20 mA VO = VCC + 0.5V +20 mA Input Rise and Fall Time (∆t/∆V) 0 ns/V to 100 ns/V −0.5V to VCC + 0.5V DC Output Voltage (VO) DC Output Source ±25 mA or Sink Current (IO) Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
